Mountain Frames

The All-City Electric Queen was expressly made for maximum fun. Sitting squarely in the “trail” category it goes up almost as well as it comes back down. Short wheelbase, modern trail geometry, and plus size tire clearance makes this a non-stop dirt party no matter what terrain you’re tackling that day. Its whippy 612 chromoly frame with internal dropper post routing, boost spacing, and those short chainstays make berm-carving and wheelies second nature. Build your Queen with 27.5+ wheels and tires with your favorite fork, drivetrain, and brakes for a dreamy rig that rules with radical energy.

The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142 x 12mm thru axle if that's your schtick, but can also be used with 135 x 10mmm QR hubs with Surly's Adapter Washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, so go wild with your build.
- 100% Surly 4130 chromoly frame, main triangle is double-butted; 1-1/8" threadless brazed chromoly fork
- Four sets of Three-Pack Mounts (two on the fork, two on the downtube), a water bottle mount on the seat tube, and front and rear rack mounts
- 142 x 12mm rear dropout (or 135 x 10mm QR with Surly 10/12 Adapter Washers) with Rohloff torque arm slot
- 135mm-spaced fork with 17.5mm offset for wheel swappability
- 26 x 4.8" tire clearance in frame (with drivetrain restrictions), 26 x 4.3" tire clearance in fork

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out.
Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It’s just as happy riding singletrack as it is parked outside your favorite drinking establishment.
Lowside is a singlespeed. Singlespeeding has been a part of Surly’s DNA since day one when we launched the 1x1 Rat Ride. After a lot of Homie Fall Fests and more feats of strength than we can recall, we decided to discontinue it a couple years back. Lowside picks up right where the 1x1 left off.
Some have dubbed the Lowside the ultimate pub cruiser.
- Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles
- Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though)
- Clearance for 26 x 3 or 27.5 x 2.8 tires

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It's your BMX bike all grown up.

The Surly Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It’s the bike you turn to when you’re not entirely sure what the night has in store. It’s the bike to grab when you want to have just as much fun riding to the trail as you do on the trail, itself. Singlespeeding is an integral part of Surly’s DNA, and the Lowside continues the tradition, by taking a simpler approach to trail riding.
- 100% Surly 4130 chromoly frame, main triangle is double-butted; 1 1/8" threadless chromoly fork
- Singlespeed "specific" (derailleur hanger: yes; Trip Guides: no)

- 26 x 3" or 27.5 x 2.8" tire clearance

Off-road touring can be a zesty enterprise, but it's not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent's basement. If you’re going to ride your bicycles where no one can see, you better take gear that's up to the task. Troll is up to the task.
Surly's Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. Surly also adorned this frame with their Gnot-Boost spacing, allowing you to use any mountain bike hub whether it be 135mm QR, 12 x 142mm thru-axle, or 12 x 148mm Boost hub. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and the complete bike comes with the always-comfy Surly Moloko Bar. The dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don't get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the downtube.
Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible. Man has known for eons the call of the indifferent forest. The inexorable march of time, and dumb things like cell phones, have dulled our senses and made us afraid. Reclaim your animalistic tendencies atop Man's greatest invention.

If you’re like us, your bike needs will likely change by the day, week, month or year. Ogre will get you to your job during the week, then way out of town on the weekend. It even has the chops to handle a cross-country trek or nine. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre is designed to be the ultimate steel utility vehicle. It relishes in those “take-the-long-way-home-and-find-some-beverages-along-the-way” sort of commutes. You can also haul enough crap on it that you don’t even have to go home if you don’t want to.
For this year, we simplified Ogre a bit. We removed the canti studs, so it is now a disc brake-only beast. Now, before you start yelling at us about how the canti studs were the only reason you were even considering buying an Ogre and now we’ve left you contemplating your very existence in this ultimately-doomed universe, hear us out. Rim brake 29er rims — like the ones that you would need to have to make use of those canti studs in the first place — are becoming increasingly harder to find. We could have given you a feature that you’d end up not really being able to use in the future but what kind of monsters do you think we are? To quench your unquenchable thirst for rim brakes, check out the Troll.
As far as other updates to the frame go, that about sums it up. Ogre still has everything else you’ve come to know and love: two water bottle mounts, four sets of three-pack bosses, mid- and low-blade fork eyelets, threaded holes for racks, fenders, and trailer mounting nuts, and a Rohloff OEM2 axle plate slot. It still features horizontal-slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefy tire clearance. It’s still fully compatible with both 29 x 2.5” and 27.5+ tires. In the complete bike version, we’ve opted to go with a 1x drivetrain and a flat handlebar.
We typically try to avoid BS cliché terms like “Do-It-All” or “Swiss Army Knife of Bikes”, so we’ll just say that Ogre can probably handle most of the ideas that are bouncing around in your head.

Wednesday is a great all-around fat bike that has the soul of a trail bike and mind of a touring bike
Wednesday sits in the middle of our Trail category, but don’t let that fool you into thinking that’s its only use. With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat bike that can truly handle anything you want to attempt.
If you do an equal amount of off-road touring as you do hitting trails, Wednesday’s ability to play both parts equally will suit you well. Or, if you’re looking for a fat bike and don’t need the fattest tires on the market, Wednesday’s 26 x 4.6" tire clearance is just the ticket.
Any day of the week’s a great day to ride a Wednesday.
- Modern mountain standards: stealth dropper post routing, 44mm headtube, suspension correction, front and rear thru-axles
- Full suite of useful braze-ons: front and rear racks, multiple sets of three-pack mounts, fenders
- Full-forward, short chainstay position: 26 x 3.8 tires on 80mm rims; full-rearward, longer chainstay position: 26 x 4.6 tires on an 80mm rim

Karate Monkey is a highly-versatile trail bike that plays the part of 29er and 27.5+ equally well.
Multipurpose Hardtail Mountain Bike
Karate Monkey delivers a resilient, lively ride on all sorts of gnarly terrain. Its frame is a highly-versatile canvas for whatever dirty masterpiece your brain cooks up. According to our computing machine (Thor) it can be set up in approximately 487 different configurations.
Originally designed as a 29er (and the frame that helped spark the 29" wheel movement), the latest Karate Monkey is designed to perform just as admirably as a 27.5+ rig as well. This allows you to pick your poison — provided your poison is having a really great time while permanently donning a maniacal grin, of course.
- Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension-corrected fork
- Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed, though)
- Clearance for 29 x 2.5 or 27.5 x 3 tires

Krampus is a dedicated 29+ trail bike that can go over, off of, or through just about anything in its path.
Breaking the Mold with a 29er Bike
As the first "plus" bike to hit the market, Krampus changed the way many people approach trail riding. It’s shown people the light of how high-volume, large-diameter tires can vastly improve the ride experience. It’s also done a bang-up job dispelling the myth that big tires make you slow.
Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, it takes trail-shredding abilities to the next level. A mullet may be business in the front, party in the back but Krampus makes partying its business.
"Lean back, hang on, and ride that wild horse." -Thor
- Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork
- Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed, though)
- Clearance for 29 x 3" tires

The ECR is Surly's answer to those times when you just need to escape to the woods for a while to get away from the humdrum of life. Those familiar with this steel mule know it’s designed around plus tires, previously of the 29” variety. A fully loaded 29+ bike is an excellent way to explore and get away for a while… if you’re of a certain stature that is. For smaller riders, it poses several challenges though. And no one wants new problems when they’re in the woods trying to escape old ones. To solve this, Surly redesigned the smaller sizes of the ECR to work with 27.5+ while the larger sizes are still equipped with 29+. All you medium specimens out there get your pick of the litter as they're offering that size in both options.
Other updates to the ECR include and are limited to: Gnot-Boost rear spacing and a killer new beige paint job. It retains the abundant accessory mounts that we all know and love like Surly Trip Guide for brakes and derailleurs, fender, rack, and Bill/Ted eyelets, and a Rohloff torque arm slot. The 27.5+ sizes also feature two sets of Three-Pack bosses. You’ve got lots of options to bring all your “necessities” with you and still have room for excess baggage if you’ve got it.

The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway.
Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight.
Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ‘ol spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy-squishy to your ride, you can throw a Bluto on and let ‘er rip.
If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise.
Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now.
*Using a 26 x 5.25" tire will cause some drivetrain limitations. For all the nuts and bolts of compatibility read Surly's blog on the subject.

It's right for you if...
You believe mountain biking isn't about racing or showing off. It's about the experience of being out there in the rough, wonderful wild. For you, every ride is both a battle against nature and an appreciation of it. There's a whole lot of beauty in dirt, rocks, and roots. Trails don't need to be perfectly sculpted to be enjoyed.
The tech you get
We call it a frameset, but it's a lot more than that! An Alpha Platinum Aluminum frame with 130mm of travel, a stiff Straight Shot down tube, Knock Block frame defense, and a FOX Float rear shock with Trek's exclusive RE:aktiv damper. Plus, a Bontrager Line 35mm stem, a headset, and a rear axle.
The final word
This is a new breed of performance backcountry trail bike. If you love seeking out the untamed trails in the wild and discovering new lines while ripping bikepacking adventures, Full Stache is your dream ride. It's like that one friend who's always egging you on to go a little farther, because there's bound to be something epic right over the next ridge or at the bottom of the next valley.
